Click the green flag then click start. There are some glitches I currently don't know how to solve; so if it doesn't complete the maze mapping then just try to reload the page. There are some plotting glitches where it tells the takeout sprite to go one direction then the other forever. Turbo Mode will break it!!
Based on an idea by griffpatch. All else coded by me. The type of maze solving is called flood filling. Flood fill is if you were to put a pipe of water at the end of a 2D maze, then pump water though it. The water would eventually reach every part of the maze, and the way it took to get there is your path to the finish.
